Rocker switches are an important type of switch in the modern world, controlling a variety of electrical and electronic applications. The KR493AKXXA12XX is such a switch, and here we look at both its application field and its working principle.

Rocker switches are used in a wide range of applications, including energy management, motor control, lighting control, and HVAC systems. The KR493AKXXA12XX in particular is designed for use in industrial applications such as machine tools, robots, and laboratory equipment.

It is a double pole, double throw rocker switch, with contacts rated at AC125/250V/440V, up to 15A and 50VA. It is UL Listed and CSA Certified, meeting stringent safety requirements for these types of applications.

The KR493AKXXA12XX has a mechanical life of more than 100,000 operations, making it extremely reliable in industrial environments. It also has a dust and splashproof design, making it resistant to foreign objects and liquids.

As far as its working principle is concerned, the KR493AKXXA12XX consists of two metallic contacts connected to an anti-vibration plunger, which is connected to a mechanical actuator. When the actuator is moved, it causes the plunger to move and the two contacts to come together or separate, depending on which direction the actuator is moved.

The plunger is held in place by a spring, which returns it back to its original position when the actuator is released. The contact patch is also made up of a special contact coating material, which ensures a good electrical connection and a long operating life.

Overall, the KR493AKXXA12XX is a reliable and robust rocker switch, suitable for a wide range of industrial applications. It is UL Listed and CSA Certified, and is designed to withstand the rigors of long-term use in these types of environments. Its working principle is based on a mechanical actuation of an anti-vibration plunger and two metallic contacts, ensuring reliable and consistent operation.
